Standards

1.1    These requirements cover the installation of lightning protection systems on all types of structures other than structures used for the production, handling, or storage of ammunition, explosives, flammable liquids or gases, and other explosive ingredients including dust.

1.2    These requirements apply to lightning protection systems that are complete and cover all parts of a structure. Partial systems are not covered by this standard.

 
1.4    Adjacent structures shall be considered separate structures.

1.5    Adjacent structures with lightning protection shall be considered part of the structure if the adjacent structure’s lightning protection system complies with this standard and is connected to the lightning protection system of the structure in accordance with Section 10.4.

1.7    Free standing Walkways shall be considered an adjacent structure under the following conditions:

     a)  It is separated by a fire wall and conductive media that is shared by both facilities has an SPD in accordance with Section 13.

1.8      This standard does not cover lightning protection for:

       a)  Electric transmission lines or open air distribution racks,

       b)  Outdoor substations or switch yards, and

       c)  Electric generators unenclosed by a building other enclosed structure.

1.9    Enclosed generators and conventional building structures at or associated with generators or power plants, etc. are covered.

1.1    These requirements cover industrial control panels intended for general industrial use, operating from a voltage of 1000 volts or less. This equipment is intended for installation in ordinary locations, in accordance with the National Electrical Code, ANSI/NFPA 70, where the ambient temperature does not exceed 40°C (104°F) maximum.

This International Standard specifies requirements for metallic, non-metallic and composite cable ties and their associated fixing devices used for the management and support of wiring systems in electrical installations.

Cable ties and associated fixing devices may also be suitable for other applications and where so used, regard should be taken of any additional requirements.

This standard does not contain requirements that evaluate any electrical insulation properties of the cable tie or mechanical protection of the cables provided by the cable tie.

This standard does not consider the mechanical interface of a fixing device to a solid surface such as a wall or ceiling.

This Technical Report presents an overview and guidance for the IEC 61158 series. It explains the structure and content of IEC 61158, shows how to use it in combination with IEC 61784, and relates the structures to the ISO/IEC 7498 OSI Basic Reference Model.
